• DETAILED DESCRIPTION

Moss Agate is an interesting variety of chalcedony, a cryptocrystalline form of quartz. Unlike classic agates, it usually does not show the typical banding but is characterized by the presence of dendritic inclusions resembling moss or tree branches. These patterns are not organic in origin but derive from iron and manganese oxides. Moss Agate is most commonly found in translucent or milky white tones with green, brown, black, or red inclusions. Its hardness on the Mohs scale ranges from 6.5 to 7, equivalent to that of common quartz. It has a waxy to dull luster and is semi-transparent to translucent. Important deposits of Moss Agate are found in India, Brazil, the United States (especially in Montana, Oregon, and Idaho), Madagascar, and Russia.
